PIERRON, J.: In this slip and fall case, Gail Barnett-Holdgraf appeals the district
court's granting of summary judgment in favor of Mutual Life Insurance Company of New
York (Mutual Life). She argues the district court erred in applying the slight defect rule and
that the evidence does not support a decision in favor of Mutual Life under the rule.

On April 23, 1996, Barnett-Holdgraf fell on a sidewalk located between two
commercial office buildings in Johnson County owned by Mutual Life. Barnett-Holdgraf
works for a tenant located in the building at 9350 Metcalf. On that day, she left her building
out the front door and walked on the front sidewalk to the 9300 Metcalf building next door.
After a meeting, she elected to leave the 9300 Metcalf building through the back door and
take the back sidewalks connecting the two buildings.

The fall occurred at the junction of two large slabs of sidewalk. Barnett-Holdgraf took
multiple pictures of the location within days after her fall. She placed a quarter in the hole
where she fell to depict the hole's depth. The pictures of the hole with the quarter in it show
half of the coin above the slab of concrete. Mutual Life argued the depth of the hole could be
no more than 1/2 inch at the point where Barnett-Holdgraf fell. Barnett-Holdgraf cites her
deposition testimony where she explained that the difference in the elevation of the sidewalk
slabs was the depth of a quarter and the hole where she fell was three quarters deep.

Barnett-Holdgraf filed a petition for damages claiming Mutual Life was negligent by
failing to protect a sidewalk common area from heaving and crumbling, failing to maintain
and repair the uneven and crumbling sidewalk, failing to give adequate and comprehensible
warning, and failing to inspect and maintain the sidewalk. Mutual Life answered the petition,
asserting Barnett-Holdgraf's claim was barred by the slight defect rule.

Mutual Life filed for summary judgment based on the slight defect rule. In her
answer, Barnett-Holdgraf admitted 10 of the 13 uncontroverted facts in Mutual Life's
statement of uncontroverted facts. She gave a limited admission to one of the remaining facts
and for the other two, she only answered "Denied" with no factual or evidentiary support to
contradict the uncontroverted facts.

Barnett-Holdgraf listed additional uncontroverted facts in her response including: (1)
the sidewalk in question was owned by Mutual Life and not by any public entity; (2) a month
prior to her fall, Mutual Life's property manager had inspected the location in question and
determined the sidewalk needed repair; (3) there was a delay in getting the sidewalk patched,
which occurred shortly after Barnett-Holdgraf's fall; (4) this was the first time Barnett-Holdgraf
had walked on the back sidewalks connecting the two buildings; and (5) she claimed
that the elevation of the sidewalk slabs in the area where she fell was about the depth of a
quarter and the hole in the slab was the depth of three quarters.

The district court granted summary judgment to Mutual Life. The court found that
Barnett-Holdgraf had failed to contradict any of the uncontroverted facts in Mutual Life's
motion for summary judgment; finding the bald unsupported statement "Denied" was
insufficient. The court also found the additional facts set forth by Barnett-Holdgraf were
immaterial to the application of the slight defect rule. The court concluded the slight defect
rule applied to the private landowner. The court then ruled the alleged defect in the sidewalk
at issue was slight and not sufficient to establish actionable negligence.

Barnett-Holdgraf argues the slight defect rule does not apply in this case because the
incident took place on a private sidewalk and not a public sidewalk.

Whether the slight defect rule applies to private sidewalks is a question of law over
which an appellate court has unlimited review. See, e.g., McGee v. Chalfant, 248
Kan. 434, Syl.
¶ 3, 806 P.2d 980 (1991) (the existence of a legal duty is a question of law over which an
appellate court exercises unlimited review).

The slight defect rule for sidewalks has been in effect for municipalities since the
Kansas Supreme Court decided Ford v. City of Kinsley, 141 Kan. 877, 44 P.2d 255
(1935). The
rule exemplifies the basic negligence formula--a risk-utility analysis in which the risk inherent
in a condition is balanced against the utility of the condition and the burden necessary to
eliminate or reduce the risk. Lyon v. Hardee's Food Systems, Inc., 250 Kan. 43, 46,
824 P.2d 198
(1992) (quoting Westerbeke and Robinson, Survey of Kansas Tort Law, 37 Kan. L.
Rev. 1005
[1989]). The court in Taggart v. Kansas City, 156 Kan. 478, 480, 134 P.2d 417
(1943), stated a
city "is not required to furnish perfect walks. Its only duty in this respect is to furnish walks
that are reasonably safe for use. [Citations omitted.] To impose a greater duty upon cities
would be to place upon them too great a financial burden." In 1985, the Supreme Court
stated that the slight defect rule adopted in Ford is just as valid now as when
announced. See
Sepulveda v. Duckwall-Alco Stores, Inc., 238 Kan. 35, 39, 708 P.2d 171
(1985).

Barnett-Holdgraf argues the slight defect rule is only applicable to public sidewalks.
However, she fails to address the language in multiple cases that seemingly hold to the
contrary. The Sepulveda court expressly stated: "It is important to note the same
rule applies
in actions against an individual or private corporation alleged to have created or maintained a
defect in the sidewalk. Roach v. Henry C. Beck Co., 201 Kan [558, 560, 442 P.2d
21 (1968)];
Pierce v. Jilka, 163 Kan. [232, 239, 181 P.2d 330 (1947)]." 238 Kan. at 38.

Barnett-Holdgraf relies heavily on Richardson v. Weckworth, 212 Kan. 84,
509 P.2d
1113 (1973), to limit the application of the slight defect rule. In Richardson, the
court stated:
"We agree with the appellee that the rule pertaining to public sidewalks and city streets
should not be universally applied in landlord-tenant litigation." 212 Kan. at 88. Barnett-Holdgraf
appears to argue that this statement equates to a holding that the slight defect rule
does not apply in any landlord-tenant litigation. This is an improper interpretation.
Richardson concerned a private sidewalk going from a garage to a house. The
sidewalk was
crumbling and full of pockmarks of various sizes. The holding in Richardson was
based on
the fact that the landlords knew of the defective sidewalk and they had repeatedly promised
the tenant they would repair the sidewalks. The Richardson court found the slight
defect rule
did not apply because of the covenant to repair leased premises as adopted by the court in
Williams v. Davis, 188 Kan. 385, 362 P.2d 641 (1961). Consequently,
Richardson is obviously
distinguishable since the case before the court involves no promise to Barnett-Holdgraf to
repair the sidewalk.

Barnett-Holdgraf also relies on Lyon v. Hardee's Food Systems, Inc., 250
Kan. 43, to
support a limiting of the slight defect rule. In Lyon, the plaintiff tripped and fell over
a tree
grate in the sidewalk that was raised above the sidewalk approximately 2 or 3 inches. The
tree grate was raised above the sidewalk due to the defendant's negligence in replacing rock
beneath the grate. Lyon does not stand for the proposition that the slight defect rule
does
not apply to private sidewalks. Rather, Lyon stands for the following rule: "The
'slight
defect rule' is not applied in cases where the irregularity in the sidewalk is created by the
negligent acts of the party against whom recovery is sought. In that case, the negligence is
actionable regardless of whether or not the irregularity is a slight defect." 250 Kan. 43, Syl.
¶

The court in Lyon set forth the following generalities concerning the slight
defect rule:

"Here, plaintiff's claim is based upon a defect negligently constructed and maintained by
the
defendant. That defect was caused by the negligent acts of the defendant and not by the acts of
nature or the passage of time. The slight defect rule is not intended to shield from liability
those who negligently create and maintain a defect in the sidewalk. Its intended function is to
limit the liability of those who permit or allow a slight defect not of their own making to
remain. The rule of a slight defect in a sidewalk does not apply where the defect is negligently
created and maintained by the defendant." 250 Kan. at 52.

The principles of the slight defect rule set forth in Ford, 141 Kan. 877, apply
equally to
the case of a private sidewalk. See Hilker v. N.P. Dodge Building Co., 184 Neb.
495, 497-98,
168 N.W.2d 701 (1969) (the rules are just as applicable to a private defendant who maintains
sidewalks for the benefit of the public, applying similar analysis regardless of whether
plaintiff was invitee or licensee). Slight defects are to be expected and, therefore, individuals
must protect themselves from injury because of them. The risk inherent in a slight defect in a
private sidewalk is outweighed by the utility of the condition and the burden necessary to
eliminate or reduce the risk of injury. The difference in the private situation is that
the of
number of sidewalks is not the same as for a city that is responsible for miles of sidewalks,
but the utility of the condition and the burden necessary to eliminate the slight defect are still
present.

"Based on our own research and consideration of the issue and the facts of this
case, we
hold the de minimis rule applies to private owners and possessors of land. A municipality is
not an insurer against all accidents and has a duty only to exercise ordinary care to keep the
sidewalks reasonably safe for persons exercising ordinary care. [Citation omitted.] Similarly,
an owner or occupier of land is not an absolute insurer of the safety of an invitee. [Citation
omitted.] The duty of an owner or occupier of any premises towards invitees is that of
reasonable care under the circumstances regarding the state of the premises or acts done or
omitted on them, and he must maintain the premises in a reasonably safe condition.
[Citations omitted.]

"As expressed in section 343 of the Restatement (Second) of Torts, the applicable
standard
of care is this:

'A possessor of land is subject to liability for physical harm caused to his invitee by
a condition on
the land if, but only if, he

(a) knows or by the exercise of reasonable care would discover the condition, and
should
realize that it involves an unreasonable risk of harm to such invitees, and

(b) should expect that they will not discover or realize the danger, or will fail to
protect
themselves against it, and

(c) fails to exercise reasonable care to protect them against the danger.'
Restatement
(Second) of Torts § 343 (1965).

"As we pointed out in our prior discussion of duty, the risk of harm must not be
merely
foreseeable, but reasonably foreseeable. A possessor of land has a duty to exercise reasonable
care to avoid creating an unreasonable risk of harm to an invitee. In applying these principles
to the case at bar, we conclude that the sidewalk in question did not have a defect such that the
risk of harm was reasonably foreseeable. Further, defendants did not create an unreasonable
risk of harm. One obvious reason that a municipality is not required to maintain perfect
sidewalks is that a large area is involved which imposes a great burden on the municipality to
maintain it. Equally important, we believe, is that extreme and changeable weather conditions
in Illinois are such that slight variations in sidewalk elevations are to be expected; sidewalks
cannot be maintained perfectly at all times. [Citation omitted.]

"It is common knowledge that sidewalks are constructed in slabs for the very
reason that
they must be allowed to expand and contract with changes in temperature."

In the case at bar, Barnett-Holdgraf presents no evidence that Mutual Life negligently
constructed and maintained the sidewalk in question, nor is there any evidence Mutual Life
promised anyone to repair the sidewalk. Rather, the facts clearly demonstrate the defect in
the sidewalk was caused by the acts of nature and the passage of time. As did the district
court below, the court in Lyon recognized the nature of Kansas weather as a major
factor in
the deterioration of sidewalks. Furthermore, all the additional facts relied upon by
Barnett-Holdgraf are secondary to an application of the slight defect rule.

The slight defect rule applies to private sidewalks. However, the rule is limited by the
applications of Richardson and Lyon.

Next, Barnett-Holdgraf argues the district court erred in granting summary judgment
to Mutual Life because it failed to consider all the evidence, and in ruling as a matter of law
that the defect was slight.

The standard of review for a case decided on summary judgment is well established.
Summary judgment is appropriate when the pleadings, depositions, answers to
interrogatories, and admissions on file, together with the affidavits, show there is no genuine
issue as to any material fact and that the moving party is entitled to judgment as a matter of
law. On appeal, we apply the same rules and where we find reasonable minds could differ as
to the conclusions drawn from the evidence, summary judgment must be denied. See
Bergstrom v. Noah, 266 Kan. 847, 871-72, 974 P.2d 531 (1999).

There is no mathematical formula or bright-line test for determining what constitutes
a slight defect, and there is some diversity of opinion as to which defects are considered
minor; each case must be determined on its own facts. Compare, for example, the Ohio
courts which apply the rule that if the sidewalk variation is 2 inches or less, the question of
whether the defect is unreasonably safe constitutes a triable issue of fact only if the plaintiff
has alleged and presented evidence of other circumstances which make the defect hazardous
notwithstanding its slight measurement. See, e.g., Stockhauser v. Archdiocese
of Cincinnati, 97
Ohio App. 3d 29, 33, 646 N.E.2d 198 (1994).

A trial court can certainly decide as a matter of law that a claim based on a slight
defect in a sidewalk is nonactionable. Courts generally rely on the well-established rule that a
sidewalk defect is actionable, that is, it presents a jury question, only when the defect is such
that a reasonably prudent person should anticipate some danger to persons walking on it. See
West v. City of Hoopeston , 146 Ill. App. 3d 538, 542, 497 N.E.2d 170 (1986). The
test
ordinarily is whether the sidewalk defects are of such magnitude or extent as to be likely to
cause injury to travelers who are proceeding with due care. See Doht v. Village of
Walthill,
207 Neb. 377, 379, 299 N.W.2d 177 (1980). To parphrase Justice Potter Stewart's now famous
statement, "We know a slight defect when we see it."

A review of the Kansas cases decided under the slight defect rule demonstrates how the
district court in the present case did not err in granting summary judgment to Mutual Life.
The landmark case in this area is Ford v. City of Kinsley, 141 Kan. 877, where the
defect
consisted of a block of cement that had sagged below the level of the adjacent blocks to a
depth between 1/2 to 3/4 of an inch. The Ford court cited several cases from other
jurisdictions to support a finding the defect was a slight defect. See Jackson v. City of
Lansing,
121 Mich. 279, 80 N.W. 8 (1899) (the top crust of a cement sidewalk had been broken off and
a depression worn therein to a depth of from 1 1/2 to 3 inches below the general level of the
walk, and the depression covered an area of 1 1/2 feet to 2 feet); Beltz v. City of
Yonkers, 148
N.Y. 67, 42 N.E. 401 (1895) (the plaintiff sought to fasten liability on the city for a fall alleged
to be attributed to a depression of 2 1/2 inches in a sidewalk); Terry v. Village of
Perry, 199
N.Y. 79, 92 N.E. 91 (1910) (actionable liability was sought to be fixed on the city on account
of a depression in a sidewalk of 1 1/2 inches).

More recently, in Roach v. Henry C. Beck Co., 201 Kan. 558, 559-60, 442
P.2d 21 (1968),
the court found slight defects where the defect was a plywood board 3/4 of an inch thick and
approximately 3 feet square covering a hole in a sidewalk. As discussed earlier, the court in
Lyon applied the slight defect rule to a tree grate in the sidewalk that was raised
above the
sidewalk approximately 2 or 3 inches. In Richardson v. Weckworth, 212 Kan. 84,
the defect
was a crumbling sidewalk full of pockmarks of various sizes.

In the present case, Barnett-Holdgraf took photographs of the sidewalk within days of
the incident. She took these pictures, at the suggestion of her attorney, for the express
purpose of showing the depth of the hole. The pictures show the concrete had spalled and
had chipped and flaked away. The pictures with the quarter in the hole show the quarter
sticking half above the concrete, which would make the hole between 1/2 inch and 1 inch
deep. The hole is also no more than 5 inches across. Mutual Life had done nothing to create
this hole, and there is no evidence to contradict a finding that the hole occurred simply by
natural causes and the passage of time.

In view of the foregoing, we do not find the district court erred in granting summary
judgment to Mutual Life. Applying the threshold tests set forth above, and even giving
Barnett-Holdgraf the benefit of the doubt that the hole was 3 inches deep, this was not such a
defect that a reasonably prudent person should have anticipated some danger to persons
walking on it, and the defect was not of such magnitude as to be likely to cause injury to
travelers who were proceeding with due care. The alleged defect in the sidewalk was slight
and therefore, as a matter of law, the defect was not sufficient to establish actionable
negligence.
